Abstract
Description
本発明は、デンプンの水性懸濁液およびある種の保存剤系を含む液体の洗濯用デンプン濃縮物、より具体的には業務用洗濯に使用するための洗濯用デンプン濃縮物、ならびに液体デンプン濃縮物における該保存剤系の使用に関する。
デンプンを含有する調製物は、洗濯物を糊付けまたは仕上げるために一般的に用いられている。これらは、比較的高い温度に暴露したとき（例えば、アイロンがけまたはしわ伸ばし中）に洗濯物においてゼラチン化するのみであり、かつ必要な硬さを与える（例えば、テーブルリンネルの場合）、ゼラチン化されていないデンプンの懸濁液として、予めゼラチン化したデンプンの溶液として、または当初はゼラチン化されていないデンプンの「煮沸物」として用いられる。また、対応する調製物は、例えば洗濯物のアイロンがけ挙動またはいわゆる感触を改良するいわゆる洗濯物の後処理用調製物の他の通常の成分を含んでいてもよい。正確な量の添加および取扱いをより簡単にするために、液体の形態で洗濯用デンプンを用いるのが有利である。これは、予め溶解した活性物質（いわゆる貯蔵液）を洗濯用ドラムまたは多区画バッチ洗濯機の特定のセクションにポンプによって自動的導入するのが普通である業務用洗濯における洗濯用デンプンの使用に特に当てはまる。このことから、本発明の調製物が満たすことが期待される要件の１つが生じる（即ち、貯蔵液を形成するその能力、または換言すると水で希釈した後の貯蔵安定性）。これは、物理学的安定性、即ち相分離（例えば、デンプンの沈降）の回避、および懸濁液の微生物学的安定性の両方に当てはまる。容易に生分解される物質であるデンプンを含む調製物は、微生物の浸入を受けやすい。この問題は、貯蔵容器で数日間貯蔵されるのが普通であり、これらの容器から添加される貯蔵液を用いる業務用洗濯において生じる必要性によって増大する。微生物の侵入がデンプン懸濁液の効果を損なわないときであっても、特に人間が感受性である微生物の場合には、洗濯用デンプンが処理した識物に残り、人間と接触することになるために、許容することができない。
懸濁液からのデンプンの分離は、いわゆるキャリアー液、例えばカルボキシメチルセルロース水溶液を用いることによって回避し得ることが知られている。しかし、使用者が要求するような多量の懸濁されたデンプンを維持するためには、カルボキシメチルセルロースの濃度は非常に高いものでなければならないので、洗濯用デンプン濃縮物の取扱いは、カルボキシメチルセルロースの増粘効果によって複雑になる。短時間の加熱（例えば４０〜６０℃）によって予めゼラチン化されたデンプン懸濁液を用いる場合には、カルボキシメチルセルロースを用いると、調製物がごく短時間の後に相当に増粘するということから問題が生じる。
ドイツ特許No.1 940 655には、デンプン懸濁液の水相として、キサンタンゴムおよび／または水溶性キサンタンゴム誘導体の溶液を含有するデンプン懸濁液が記載されている。デンプンは、この方法で沈降から効果的に防止される。
微生物侵入に対する安定性を増大させるために、引用した文献においてはホルムアルデヒドのような従来の殺菌剤を用いることが提案されている。ホルムアルデヒドのような殺菌剤はデンプン処理した洗濯物に残るので、ここでも使用者との接触および使用者への影響の危険性が存在する。この結果、好ましい抗微生物活性にもかかわらず、ホルムアルデヒドおよび他のアルデヒド、フェノールならびに活性塩素を放出する物質を使用することができない。
従って、本発明の指向する課題は、一方において洗濯用デンプン濃縮物およびこれから調製した水性貯蔵液の微生物侵入を確実に防止し、他方において使用者に影響を及ぼす可能性のある量または活性でデンプン処理洗濯物に残存することのない洗濯用デンプン濃縮物のための保存剤を提供することであった。
この課題は、大きくは、キサンタン水溶液に懸濁したデンプンまたはデンプン誘導体を含む水性の洗濯用デンプン濃縮物を保存するために、一般式（Ｉ）：
R1R2(CH3)2N+A- (I)
[式中、R1およびR2は、互いに独立して、8〜18個の炭素原子、より具体的には8〜10個の炭素原子を含有する直鎖または分岐鎖アルキル基であり、A-は、電荷対等化陰イオン、例えばハロゲン化物（例えば、塩化物、臭化物、ヨウ化物、フッ化物）、メトスルフェートまたはエトスルフェートである]
で示される第四級アンモニウム化合物およびエタノールの組合せ物を使用することによって解決された。
本発明に従って用いる組合せ物において、成分エタノールと第四級アンモニウム化合物の重量比は、好ましくは5,000：1〜1：1、より好ましくは400：1〜10：1である。本発明に従って用いる組合せ物は、液体の形態で存在するのが好ましく、例えば、成分を供給する特定の形態に由来する他の成分を含むこともできる。即ち、エタノールは、水に加えていわゆる変性剤（例えば、メチルエチルケトン）を含むことが多く、一方、第四級アンモニウム化合物は、水に加えてエタノール以外の他の低級アルコール（例えば、イソプロパノール）を含む調製物の形態で市販されている。
本発明に従って用いる組合せ物は、濃縮物を保存するために、100重量部の液体洗濯用デンプン濃縮物全体を基準に、好ましくは1〜10重量部の量で、より好ましくは2〜8重量部の量で用いる。
また、本発明は一般式(I)：
R1R2(CH3)2N+A- (I)
[式中、R1およびR2は、互いに独立して、8〜18個の炭素原子、より具体的に8〜10個の炭素原子を含有する直鎖または分岐鎖アルキル基であり、A-は、電荷対等化陰イオン、例えばハロゲン化物（例えば、塩化物、臭化物、ヨウ化物、フッ化物）、メトスルフェートまたはエトスルフェートである]
で示される第四級アンモニウム化合物とエタノールを含むことを特徴とする、キサンタン水溶液中に懸濁したデンプンまたはデンプン誘導体を含む液体洗濯用デンプン濃縮物に関する。エタノールは、本発明の調製物中に、好ましくは1〜10重量％、より好ましくは2〜8重量％の量で存在するが、一方、一般式(I)で示される第四級アンモニウム化合物は、好ましくは0.002〜0.5重量％、より好ましくは0.02〜0.2重量％の量で存在する。一般式(I)で示される第四級アンモニウム化合物において、Ｒ1はＲ2と同一であるのが好ましい。好ましいアルキル基Ｒ1およびＲ2はデシル基、より具体的にはn-デシル基である。エタノールおよび一般式(I)の第四級アンモニウム化合物は、本発明に従って用いる組合せ物の形態でまたは独立して、本発明の調製物に導入することができる。
用いるデンプンは、顆粒または粉末形態で存在する任意のデンプンおよびデンプン誘導体（例えばコーンデンプン、米デンプン、ジャガイモデンプンおよび／またはタピオカデンプン）から選択してよい。天然の形態で存在するのが好ましいが、熱的、加水分解的または酸化的に減成されていてもよい。また、本発明におけるデンプンは、冷水にほとんど不溶性であり、かつ熱水中でゼラチン化する任意のデンプン誘導体をも包含する。デンプンは、好ましくは10〜50重量％、より好ましくは20〜45重量％の量で本発明の調製物中に存在する。
デンプンの沈降に対する安定化のために、本発明の水性調製物は、例えば、ケルザン(KelzanR)、ロドポール(RhodopolR)、ケトロール(KetrolR)またはレオザン(RheozanR)の製品名で市販されている水溶性キサンタンを含有する。キサンタンは、グルコースまたはデンプンの水溶液から細菌株キサントーマス・カンペストリス(Xanthomas campestris)によって産生されるものに対応するポリサッカリドであると理解されている(J.

Vol. III(1961), p51〜63)。これは、主にグルコース、マンノース、グルクロン酸およびこれらのアセチル化生成物からなり、さらに少量の化学結合したピルビン酸を含む。例えば、エチレンオキシド、プロピレンオキシドおよび／またはブチレンオキシドによるアルコキシル化によって、例えば、ハロゲン化メチルおよび／または硫酸ジメチルによるアルキル化によって、カルボン酸ハロゲン化物によるアシル化によって、またはケン化性の脱アセチル化によって得られる水溶性キサンタン誘導体を用いることもできる。キサンタンは、好ましくは0.1〜2重量％、より好ましくは0.2〜1.5重量％の量で本発明の調製物中に存在する。これは、室温で好ましくは500〜10,000mPa・s、より好ましくは1,000〜6,000mPa・sの範囲である本発明の洗濯用デンプン濃縮物の粘度に大きく寄与する。キサンタンを使用する特別の利点は、−5〜40℃の広い温度範囲にわたって粘度変化が非常に少なく、この温度範囲を超えたときであっても、この調製物が室温に戻ったときに上記の好ましい粘度範囲の値が可逆的に再度得られることである。
本発明の液体の洗濯用デンプン濃縮物は、このような調製物に普通に使用される任意の成分をさらに含むことができる。これら成分には、例えば潤滑剤、陰イオン性および／または非イオン性界面活性剤、水混和性溶媒、例えば乳化剤、例えばエチレングリコールおよび／またはグリセロール、光沢剤、例えばホウ砂、ならびに染料および香料が含まれる。水は、本発明の調製物中に好ましくは40〜90重量％、より好ましくは45〜80重量％の量で存在する。
液体洗濯用デンプンを使用するために、本発明の濃縮物を、0.5〜10g／lのデンプンを含む即時使用用の溶液が得られる程度にまで水で希釈してもよい。この溶液は、家庭で手によってまたは通常の洗濯機のすすぎサイクルにおけるすすぎ溶液として用いることもできる。業務用洗濯において用いる場合には、本発明の調製物を、1kgの乾燥洗濯物あたり好ましくは2〜30kgの量で最終すすぎ槽に添加する。
実施例
成分を単に混合することによって、以下の表1に示す組成を有する洗濯用デンプン濃縮物M1を調製した。この目的のために、水を最初に導入し、約80℃に加熱し、次いでPEGトリグリセリド、ホウ砂およびグリセロールを混ぜ込み、次いで30℃以下まで冷却し、水で希釈したエタノールを添加し、コーンデンプンを混ぜ込み、キサンタンおよびQUATの水性混合物を添加し、全体を香料と混合した。調製物は、pH7.9を有し、デンプンが顕著に沈降することなく−10〜50℃の温度で少なくとも24時間は貯蔵安定性であり、その粘度（室温で測定）はほとんど変化しなかった。
Preparations containing starch are commonly used to glue or finish laundry. These only gelatinize in the laundry when exposed to relatively high temperatures (eg during ironing or wrinkling) and give the required hardness (eg in the case of table linens) It is used as a suspension of unstarved starch, as a solution of pregelatinized starch, or as a “boiler” of starch that is not initially gelatinized. Corresponding preparations may also contain other conventional ingredients of so-called laundry post-treatment preparations which improve, for example, the ironing behavior or the so-called feel of the laundry. To make the correct amount addition and handling easier, it is advantageous to use the laundry starch in liquid form. This is especially true for the use of laundry starch in commercial laundry, where it is common to pump a pre-dissolved active substance (so-called stock solution) automatically into a particular section of a laundry drum or multi-compartment batch washer. apply. This results in one of the requirements that the preparation of the present invention is expected to meet (ie its ability to form a stock solution, or in other words storage stability after dilution with water). This applies to both physical stability, i.e. avoidance of phase separation (e.g. starch sedimentation) and microbiological stability of the suspension. Preparations containing starch, an easily biodegradable material, are susceptible to microbial infiltration. This problem is usually stored in storage containers for several days and is exacerbated by the need that arises in commercial laundry using storage liquids added from these containers. Even when the invasion of microorganisms does not impair the effectiveness of the starch suspension, especially in the case of microorganisms that are sensitive to humans, the laundry starch will remain on the treated object and come into contact with humans. It is not acceptable.
It is known that the separation of starch from the suspension can be avoided by using so-called carrier liquids, for example aqueous carboxymethylcellulose solutions. However, in order to maintain a large amount of suspended starch as required by the user, the concentration of carboxymethylcellulose must be very high, so the handling of laundry starch concentrate should be Complicated by thickening effect. When using starch suspensions pregelatinized by brief heating (eg 40-60 ° C.), the use of carboxymethylcellulose is problematic because the preparation thickens considerably after a very short time. Occurs.
German Patent No. 1 940 655 describes a starch suspension containing a solution of xanthan gum and / or a water-soluble xanthan gum derivative as the aqueous phase of the starch suspension. Starch is effectively prevented from settling in this way.
In order to increase the stability against microbial invasion, it is proposed in the cited literature to use conventional fungicides such as formaldehyde. Since germicidal agents such as formaldehyde remain in starch-treated laundry, there is also a risk of user contact and user impact here. As a result, in spite of favorable antimicrobial activity, substances that release formaldehyde and other aldehydes, phenols and active chlorine cannot be used.
Accordingly, the problem addressed by the present invention is to ensure that on one hand the starch concentrate for washing and the aqueous stock prepared therefrom are prevented from microbial invasion and on the other hand starch in an amount or activity that may affect the user. It was to provide a preservative for a laundry starch concentrate that does not remain in the treated laundry.
This task is largely directed to preserving aqueous laundry starch concentrates comprising starch or starch derivatives suspended in an aqueous xanthan solution, having the general formula (I):
R 1 R 2 (CH 3) 2 N + A - (I)
[Wherein R 1 and R 2 are, independently of each other, a linear or branched alkyl group containing 8 to 18 carbon atoms, more specifically 8 to 10 carbon atoms; - a charge equal hung ions such as halides (e.g., chloride, bromide, iodide, fluoride), a methosulfate or ethosulfate]
This was solved by using a combination of a quaternary ammonium compound and ethanol as shown in FIG.
In the combination used according to the invention, the weight ratio of the component ethanol to the quaternary ammonium compound is preferably 5,000: 1 to 1: 1, more preferably 400: 1 to 10: 1. Combinations used according to the present invention are preferably present in liquid form, and may include other ingredients derived from the particular form supplying the ingredients, for example. That is, ethanol often contains so-called modifiers (eg, methyl ethyl ketone) in addition to water, while quaternary ammonium compounds contain other lower alcohols (eg, isopropanol) other than ethanol in addition to water. Commercially available in the form of a preparation.
The combination used according to the invention is preferably in an amount of 1-10 parts by weight, more preferably 2-8 parts by weight, based on the total 100 parts by weight of liquid laundry starch concentrate, in order to preserve the concentrate. Used in the amount of
The present invention also provides a compound represented by the general formula (I):
R 1 R 2 (CH 3) 2 N + A - (I)
Wherein R 1 and R 2 are, independently of each other, a linear or branched alkyl group containing 8 to 18 carbon atoms, more specifically 8 to 10 carbon atoms, and A − Is a charge-paired anion, such as a halide (eg, chloride, bromide, iodide, fluoride), methosulfate or ethosulfate]
A starch concentrate for liquid laundry comprising starch or a starch derivative suspended in an aqueous xanthan solution, comprising a quaternary ammonium compound represented by Ethanol is preferably present in the preparation of the invention in an amount of 1 to 10% by weight, more preferably 2 to 8% by weight, whereas the quaternary ammonium compound of the general formula (I) is , Preferably 0.002 to 0.5% by weight, more preferably 0.02 to 0.2% by weight. In the quaternary ammonium compound represented by the general formula (I), R 1 is preferably the same as R 2 . Preferred alkyl groups R 1 and R 2 are decyl groups, more specifically n-decyl groups. Ethanol and the quaternary ammonium compound of the general formula (I) can be introduced in the preparation of the invention in the form of a combination used according to the invention or independently.
The starch used may be selected from any starch and starch derivatives present in granular or powder form (eg corn starch, rice starch, potato starch and / or tapioca starch). It is preferably present in its natural form, but may be degraded thermally, hydrolytically or oxidatively. The starch in the present invention also includes any starch derivative that is almost insoluble in cold water and gelatinizes in hot water. Starch is preferably present in the preparation of the present invention in an amount of 10-50% by weight, more preferably 20-45% by weight.
For stabilization against sedimentation of the starch, the aqueous preparations of the present invention, for example, Kelzan (Kelzan R), Rodoporu (Rhodopol R), commercially available under the trade name Ketororu (Ketrol R) or Reozan (Rheozan R) Contains water-soluble xanthan. Xanthan is understood to be a polysaccharide corresponding to that produced by the bacterial strain Xanthomas campestris from an aqueous solution of glucose or starch (J. Biochem. Microbiol. Technol. Engineer. Vol. III). (1961), p51-63). It consists mainly of glucose, mannose, glucuronic acid and their acetylated products, and contains a small amount of chemically bound pyruvate. For example, obtained by alkoxylation with ethylene oxide, propylene oxide and / or butylene oxide, for example by alkylation with methyl halide and / or dimethyl sulfate, by acylation with carboxylic acid halides, or by saponifiable deacetylation. Water-soluble xanthan derivatives that can be used can also be used. Xanthan is preferably present in the preparation of the present invention in an amount of 0.1-2% by weight, more preferably 0.2-1.5% by weight. This greatly contributes to the viscosity of the laundry starch concentrate of the present invention, which is preferably in the range of 500 to 10,000 mPa · s, more preferably 1,000 to 6,000 mPa · s at room temperature. The particular advantage of using xanthan is that there is very little change in viscosity over a wide temperature range of -5 to 40 ° C., and even when this temperature range is exceeded, when the preparation returns to room temperature, A preferred viscosity range value is obtained reversibly again.
The liquid laundry starch concentrate of the present invention can further comprise any ingredients commonly used in such preparations. These ingredients include, for example, lubricants, anionic and / or nonionic surfactants, water-miscible solvents such as emulsifiers such as ethylene glycol and / or glycerol, brighteners such as borax, and dyes and fragrances. included. Water is preferably present in the preparation of the present invention in an amount of 40-90% by weight, more preferably 45-80% by weight.
In order to use liquid laundry starch, the concentrate of the present invention may be diluted with water to such an extent that a ready-to-use solution containing 0.5-10 g / l starch is obtained. This solution can also be used by hand at home or as a rinse solution in a normal washing machine rinse cycle. When used in commercial laundry, the preparations of the invention are added to the final rinse tank in an amount of preferably 2-30 kg per kg of dry laundry.
Examples A laundry starch concentrate M1 having the composition shown in Table 1 below was prepared by simply mixing the ingredients. For this purpose, water is first introduced and heated to about 80 ° C., then mixed with PEG triglycerides, borax and glycerol, then cooled to below 30 ° C., ethanol diluted with water is added, corn Starch was mixed and an aqueous mixture of xanthan and QUAT was added and the whole was mixed with the fragrance. The preparation had a pH of 7.9, was stable at storage at a temperature of −10 to 50 ° C. for at least 24 hours without significant sedimentation of the starch, and its viscosity (measured at room temperature) changed little. .
